necting plumbingfixtures with closet bends,

and is particularly adapted for floor con-, nections of water closets.

The object of the invention is to provide a device of this class whichwill be gas and water tight. 3

The invention consists primarily in providing a closet bend with aplurality of diametrically opposed lugs in different horizontal planes,which lugs are adapted to be engaged by a plurality of inclined tracksformed upon a floor plate surrounding the discharge opening from thecloset bowl.

The invention further consists in provich ing said inclined tracks witha plurality of lug engaging steps which are adapted to lock the floorplate in adjusted position and prevent retrograde movement thereof.

The invention consists further in certain novel features of constructionand arrangement of parts which will be fully understood by reference tothe description of the drawings and to the claims hereinafter given.

Of the drawings Figure 1 represents a vertical section of a connectionembodying the features of the present invention. Fig.

\ 2 represents a horizontal section thereof, the

cutting plane being on line 22 on Fig. 1. Fig. 3 represents an elevationof the upper end of an iron closet bend, and showing a plurality ofoutwardly extending lugs thereon in different horizontal planes. Fig. 1represents an elevation of the upper end of a lead bend having a collarsecured thereto provided with outwardly extending lugs and a floor platesurrounding the same. Fig. 5 represents a similar view showing thefloorplate about to be engaged with one of the outwardly extending lugs. Fig.6 represents a horizontal section of a portion of one of said floorplates. Fig. 7 represents a vertical section of a modified form ofcloset connection in which the floor plate is provided with a downwardlyextending cylindrical wall having extending inwardly therefrom inclinedstepped flanges adapted to coact with the outwardly extending lugs onthe closet bend. Fig. 8 represents a plan of the floor plate and thecloset bend engaged therewith, and Fig. 9 represents an insideelevationof a portion of said floor plate.

Similar characters designate like parts throughout the several figuresof the drawings.

In. the drawings, 10 represents a closet bend preferably having formedintegral therewith a pluralityvof outwardly extending lugs 11 indifferent horizontal planes, the lugs in one of said planes beingadapted to be engaged by means of an inclined track formed upona'cylindrical hub 13 of a floor plate 1-1, the under face of which isadapted to rest-upon the upper face of a floor 15. The cylindrical hub13 is adapted to surround the upper end of the closet bend 10. When thehub '13 is provided'with the inclined tracks 12 cutthrough the wallthereof as indicatedin Figs. 4 and 5 of the drawings, the inner wall ofsaid hub is adapted to fit closely to the outer wall of the closet bend10 or the outer wall of a collar 16 fitted over and secured to saidcloset bend 10 when the latter is formed of lead.

It is obvious that when the closet bend 10 is made of lead, as indicatedin Fig. 1 of the drawings, it is essential that a collar of brass orsome other material be secured thereto, having formed thereon or securedthereto the outwardly extending lugs 11. Each inclined track 12 isprovided with a plurality of depressions or steps 17 with which the lugs11 are adapted to engage to lock the fioorfplate 14 inadjustedposition'relative i to the closet bend 10 and clamp it againstthe floor. The floor, plate 14: is inclosed by the recessed base portion18 of a watercloset bowl 19, only the discharge portion of which isshown in the drawings. extending flange of the floor platelet is Theoutwardly provided with a plurality of slots 20 concentric withthecylindrical hub 13 thereof, and through these slots 20 extend the headedbolts 21 the outer ends of which are threaded to thenuts 22by which thefloor plate and base portion '18 of the waterclosetbowl are securelyclamped together, a packing member 23 being interposed between these twoelements. .1 Owing to the inclined or curved outer face of this packingmember 23 it is obvious that it will be more firmly pressed into contactwith the outer wall of the sleeve 16 or closet bend as the case may bewhen the inner wall of the base portion 18 is moved toward the floorplate 14 by means of the adjusting nuts 22.

When the bowl is of the spigot type in i 0 on which are formed theinclined lug engaging tracks 12, each track having a plurality of stepsor depressions 17 formed therein. From the upper end of each inclinedflange 2st extends downwardly a wall 25 the lower end of which isseparated from the lower end of the next track 12 a distance. somewhatgreater than the thickness of one of the out wardly extending lugs 11 asindicated at 26 in Fig. 9 of the drawings. This affords an opportunityfor the lugs 11 to enter the annularhub 13 so that the floor plate 14:may be moved about its axis independently of thewatercloset bowl 19 andthe bend 10 sufficiently to adjust the upper end of the closet bend 10above the upper surface of the floor 15 so that when the bowl 19 ispositioned it will compress tosome extent the packing 23 interposedbetween the upper end of the closet bend and the lower face of therecessed base portion 18. Then this adj ustment has been made theopenings 26 may be closed up with oakum and then the space between theinner wall of the hub 18 and the outer wall of the closet bend 10 isfilled with lead, as indicated at 27 in Fig. 7 of the drawings.

7 Where an ironcloset bend 10 is used it is provided with a plurality ofannular incisions 28, these incisions being for the purpose offacilitating the shortening Q of the end of the bend 10 by removing oneor more sections thereof. Where the closet bend is made of lead it isobvious that a section may be readily cut from the end thereof .and thebrass collar 16 soldered in any desired position thereon. This makes avery simple form of floor connection which is very effective 1noperatlon, securing as 1t does an absolutely gas and water tlght oint.

It s believed that the operation and many advantages of the inventionwill be fully understood from the foregoing description. i-Iavin'g thusdescribed my invention, I claim: 7
